if you are not going to keep a set of winter tires on hand.... I strongly recomend the Dunlop SP Sport A2's! Mine are awsome and they kept me straight when everyone else was going sideways during the huge storm we had 3 weeks ago. They are just as good in the rain as the origanal tires that came on my teg and they are better then the 5000's in the dry!
thay are also damn cheap
